imcannomznm To all whom it may concern:

Be it known that I, ADOLFO DE CLAIR- MoN'r,'citizen of the UnitedStates, residing at Toledo, in the county of Lucas and State .of Ohio,have invented certain new and usea 'decarbonizing fluid into thecylinder while the engine is running and the cylinder thus heated torender the action of the decarbonizing fluid thoroughly effective.

The invention has as a further object to provide a device of thischaracter wherein the decarbonizing fluid will be admitted into theengine cylinder a little at a time in order that the greatest cumulativeefi'ect tending to soften and disintegrate any car- Specification ofLetters Patent.

the container into a supply chamber 13 for bon collected within thecylinder may beobtained from a given volume of liquid.

And a still further object .of the invention is to provide aconstruction wherein a small quantity of decarbonizing fluid will beadmitted to the engine cylinder at each down wa'rd stroke of the pistonthereof to the end that the piston upon its alternate upward strokeswill force the heated decanbonizing fluid to all exposed surfaces of thefiring chamber of the cylinder and into the pores of the carboncollected thereon for softening and dissolving the carbon, so that whenthe cylinder is later fired, in the usual manner, the disintegratedcarbon will be burned and discharged therefrom.

' my improved decarbonizer, and

Fig. 2 is a side elevation showing the manner in which the deviceisattached to an engine cylinder. the engine shown being conventionallyillustrated.

In carrying the invention into effect I employ a preferably cylindricalhollow body or container 10 which is formed with decarbonizing liquidand a suction chamber 14. At its lower extremity the pi e 12 projectsthrough the bottom wall of the container and threaded upon the lowerterminal of the said pipe is a pet cock 15 which may be of any approveddesign but, at its lower end is preferably formed with a universalthread to enter a bushing or adapter whereby the device may be readilycon- 1 nected with differing spark plug openings of various types ofengines. The valve of the pet cock is indicated at 16.

Threaded upon the upper end of the container 10 is a cap 17 thereforpreferably held against accidental displacement by a set screw 18. Thiscap is formed axially with an upstanding reduced neck 19 into which'isremovably threaded a closure plug 20 overlying the neck and adapted toseat against the upper edge thereof. Formed axially through the plug isa passage 21 en- .larged at its upper end to form a chamber for a plugvalve 22 removably threaded into the said chamber. The valve 22 isprovided at its upperend with an" enlarged milled head 23 overhangingthe upper end of the closure plug and adapted to seat thereagainst. Thisvalve is adapted to normally close the passage 21 through the closureplug and, as will be understood, the milled head of the valve may bereadily grasped for rotatably opening the valve.

Threaded into the passage 21 at the inner end of the closure plug 20 1sa valve cage 24 opening into the passage and in which is mounted aninwardly opening air intake ball valve 25 normally held to its seat inclosed position by a spring 26 within the cage. Formed'in the stand pipe12 adjacent its lower end is an internal annular shoulder 27 andthreaded through this shoulder is a valve cage 28 similar to the cage 24and upper end I communicating "with the suction chamber normally held toits seat in closed position by a spring 30 within the cage. In thisconnection it is to be noted that the spring li of the valve isrelatively light while the spring of the valve 29 is considerablyheavier. The purpose of this arrangement will presently appear.Extending vertically along the outer side of the stand pipe 12 andsecured to the said pipe in any approved manner. are relatively smallfeed pipes 31. Sue, two. or more of these pipes may be employed spacedpoints around the stand pipe. as found most desirable. At, their lowerends. the pipes 31 terminate adjacent the bottom of the supply chamber13. At their upper ends these pipes are formed with crooked terminals 32engaging over the upper end edge of the stand pipe and extendingdownwardly within the upper end portion thereof.

In Fig. 2 of the drawings. 1 have shown my improved device in connectionwith an internal combustion engine 33. of conventional type. Inpractical use the decarbonizer is designed for selective attachment tothe cylinders of an engine at the spark plug openings therein and inthis figure of the drawings 1 have illustrated the device so connectedto the front cylinder of the engine 33. the spark plug of the saidcylinder being. of course. first removed. when the lower end of the petcook 15 is operatively connected with the spark plug opening of thecylinder. The engine is then started and is run until the cylinder andits associated parts become thoroughly heated. when the closure plug 20of the container 10 .is removed and a charge of suitable decarbonizingliquid. such as coal oil. introduced into the supply chamber 13 of thecontainer. In this connection it will be observed that the closure plugtogether with the valve cage 24: and valve 25 as well as the plug valve22. may be bodily displaced from the cap 17. thus permitting thedecarbonizing fluid to be readily introduced into the container throughthe neck 19 at the top thereof. Having tilled the supply chamber. theclosure plug is then replaced. it being. of course. understood thatduring the operation of filling the supply chamber. the valve 16 of thepet cock is closed. This valve is then. while the engine is stillrunning. opened. Thus communication will be established between thecylinder and the suction chamber 14: so that upon the first ensuingdownward stroke of the piston ofthe cylinder. 3. partial vacuum will becreated within said chamber acting upon the discharge ends of the feedpipes 31 at the upper end of the said chamher, to pump up from thesupply chamber 13. a small quantity of the decarbonizing thud to bedischarged into the suction chamber. Thesuction created by the cylinderpiston in its downward movement will also.

as will be seen. act to unseat the discharge valve so that the smallquantity of decarbonizing fluid delivered into the. suction chamber i lwill be drawn into the engine cylinder. Consequently, upon the followingupward stroke of the cylinder piston say for instance, its compressionstroke, the small quantity of decarbonizing fluid introduced into thecylinder will be difi'used to practically all of the exposed surfaceswithin the firing chamber of the cylinder and will be forced into thepores of any carbon collected thereon. Thus, since the cylinder isheated by the runnin of the engine. the decarbonizing fluid will bethoroughly heated upon its initial introduction into the cylinder and.in being subjected to the pressure created by the compression stroke ofthe piston. will permeate the carbon within the cylinder for effectuallysoftening and disintegrating the carbon. After the first downward strokeof the cylinder piston. as just described. the air within the container10 will have been exhausted to such extent that, in order to permit thepumping of a quantity of the decarbonizing fluid through the feed pipesupon the next downward stroke of the piston. or. in the instance taken.itsfiring stroke. air must be admitted into the container. Accordingly.the plug valve 22 is opened up a quarter turn more or less. Air willthus be permitted to flow in between the threads of the plug valve andthe neck 19 of the cap and past the intake valve 25 to destroy thepartial vacuum in the container. Then, upon the firing stroke of thecylinder piston. another small quantity, of decarbonizing fluid will. aspreviously described, be introduced into the cylinder. This secondcharge of fluid will. of course. be immediately heated within thecylinder and will further act upon the carbon within the firing chamberfor disintegrating the carbon. This action will continue as the enginecontinues to run. a small quantity of decarbonizing fluid beingintroduced into the cylinder at each down stroke of its piston. Thus,the maximum effect tending to soften. disintegrate and dissolve thecarbon within the cylinder will be obtained from a given quantity ofdecarbonizing fluid due to the gradual application of the fluid withinthe cylinder and. in order to permit the pumping of the decarbonizingfluid from the supply chamber 13, during the continued operation of thedevice, the plugvalve 22 is gradually opened to permit a free flow ofair into the container. Having exhausted all of the decarbonizing fluidfrom the container, the decarbonizer is then removed and the spark plugof the cylinder replaced when. upon the firing of the cylinder, thesoftened and disintegrated carbon therein will be burned and dischargedfrom the cylinder.

Owing to the extreme suction created by the cylinder piston in itsdownward stroke and acting to unseat the valve 29, the spring 30 isrelatively heavy to resist such suction considerablyin order that saidvalve may not be unduly opened to permit an undesired sudden dischargeof all of the liquid pumped into the suction chamber 1.4:. This springis preferably of such tension that the discharge valve will bepermittedto open sufliciently to allow only a gradual escape of a-pumpedcharge of the liquid past the valve, so that said char e will begradually fed into the cylinder. owever, since it is important toprevent the formation of such the container when the plug valve isopened.

The purpose in employing the relatively light and heavysprings 26 and 30in connection with the intake and discharge valves accordingly nowbecomes apparent. In this connection it is to be observed that while thedischarge valve will serve as a primary check to the suction within theengine cylinder, the feed tubes will, owing to their.

relatively small diameter, also furnish a check to the cylinder suctiontending to regulate the flow of liquid pumped from a highly effectiveconstruction'for the purthe supply chamber into the suction chamber. Thefeed tubes will, therefore, constitute a secondary suction checkingmeans auxiliary to the primary checking means constituted inthedischarge valve. As is well known the partial vacuum produced indifferent engine cylinders varies quite widely and it accordinglybecomes imperative to provide some means for effectually checking theflow of liquid under the action of extreme cylinder suction. Iaccordingly employ the feed tubes 31 between the supply chamber and thesuction chamber of the device. These feed tubes will prevent the entryof liquid into the suction chamber except in small quantities without.regard to variance in cylinder suction so. that the decarbonizing liquid'will always be introduced into the cylinder in small quantities. Itwill, therefore, be seen that I provlde pose set forth. In thisconnection it will, of course, be understood that the decarbonizer isapplied to each of the cylinders of the engine successively, and eachcylinder treated in the manner previously described.

Furthermore, it will be,seen that while I have indicated that the deviceis connected directly with each cylinder of the engine at its spark plugopening, the device may, nevertheless, be mounted at some convenientpoint adjacent to the engine and-a pipe led therefrom and successivelyconnected with lift liquid from the first chamber suction in the latterchamber will act. to
